SEED-TREATING MACHINE.

Application filed. September 12, 1924. Serial No. 737,284.

My present invention relates to improvements in seed treatingr machines wherein the seed or grains for planting are treated or coated with a powder as a preservative against disease as smut which attacks the seed or grain after planting. The line dust accompanying the' powders usually employed is of such nature that if permitted to ente-r the lungs of the attendant or operator of the machine, or other person, it has a veryF deleterious effect.

The primary object of my invention is the provision of a pneumatic attachment for these seed treating machines by means of which the excess powder or dust may be gathered at the seed discharge end of the machine, conveyed away, and disposed of at a. suitable distant point, as at the outside ci" the building in which the machine is operating.

By the utilization of the attachment of my invention a device is provided which comparatively inexpensive in cost of pro duction, simule in construction and operation, and is eliicient in the performance of its Functions.

rThe invention consists in certain novel combinations and arrangement-s of parts of the attachment will hereinafter be more fuliyset forth and claimed.

if the accompanying drawings I have lu trated one complete example of the ihysical linbodiment of my invention whereu ',he irirts are combined and arranged in ce with the best mode l have thus 'ar 'ed for the practical application of he principles of my invention.

YFigure i is a View in perspective showing in dotted lines a well known type of seed treating` machine, with the device of my invention attached to said machine in operative position and shown in full lines.

Figure 2 is an enlarged, vertical sectional view of the fan blower and attachment.

li`igure 3 is a view showing the seed discharge spouts, with seed bags in dotted lines, and illustrating the relation of the dust gathering, pneumatic head.

Figure l is a view of the pneumatic head, detached, as viewed from its inner side.

in order that the general assembly and relation of parts may readily be understood l have shown a4 conventional form of seed 'treating machine supported on a frame l, and indicated at 2 the rotary type of seed treating machine wherein the seed and powder are mixed, the seed and powder being' supplied at the feed end 3 and the coated seed being discharged at the rear end 4 of the machine. i i

A pair of angularly disposethdiverging discharge spouts 5 and 6 are secured to the frame of the machine by straps 7 and 8, and the treated `grain is discharged through these spouts to the respective gatl'iering` bags 9 and l0 shown in dotted iines in Figure 3. At the discharge end of the machine, the unconiined excesspowder and fine dust of the treating element are caught or gathered by the utilization of the device of my invention, and thus prevented from permeating the atmosphere at this point.

My attachment for gathering the dust. includes a fen blower casing l1, supported below and at one side of the machine on a frame l2, in which the fan or blast` wheel l?) enclosed.

The fan shaft let is journaled in bearings l5, `and the blower, which is of the centrifugal type with bottom horizontal discharge is provided with a central intake pipe 16 around which is also provided au opening 17 for gathering dust adjacent to the opening, as indicated by the arrows in Figure 2. The gathered dust is airswept through the bottom horizontal discharge pipe 18 from the fan casing to the exterior of the building' containing the machine and freed to the atmosphere, or if desired means may be provided for the recovery of this excess dust and powder.

At the upper free end of the intake pipe i6 I provide a telesooping, adjustable, pneumatic head, for gathering the dust, and through which head the gathered dust is passed, and conveyed through the intake pipe to the blower. The intake head is fashioned with a sleeve 19, circular in this instance to conform to the shape of the intake pipe 16 into which it telescopes and within which it may be adjusted to proper position.

The head is fashioned with a pair of angularly disposed dust gatherers and 2l integral. with the sleeve and open thereto. These dust gatherers are in the form of rectangular boxes with open outer ends, and each has an open face or side bounded by flanges 22. The boxes are rectangular in cross section and disposed at approxiloo spouts and 6 of the discharge end of theV The angular boxes are designed to fit in between the divergingspouts with machine.

their open faces against the outer walls of the spouts, and atta-ching straps 23 on the boxes are employed to secure the. boxes to the spouts. The boxes thus forni open'end intakes for gathering the dust from thepup- .per ends of the bags 9 and l0, which as seen 1n Fig. 3 enclose the. ends of the .boxes and spouts.y VVh'ile the suction of the. fan

is suflicient to gather the dust from the tops f of'ythefbags7 it is not sulicientto affect the 'movement of the treated seed as they are discharged into the bags, and in this manner the dust is .separated from -the seeds and suitably disposed of.

The fan blower may be operated from the operating parte of the seed treatingl 1nachine througha belt .passing over the pulley 24.

ItW-ill-l be notedin Figure 3 that the boxes.

and Qlare. slightly shorter than the spouts 5 and 6, i. efthe open ends .of the 'boxes ter- Y f minatefback of the open ends of the speuts .thus decreasing the likelihood .of ther draft or suction .of air affecting the inovement'of the grain oriseed. Any-dust escaping from the bags or `sacks would be Lgathered to the fan casing through thei .intake opening 17 of the fancasing .which is located sufficiently l close to the discharge end of the machine to accomplish this purpose. I

Having thuswfully described my invention, what I claim as new and desire to secure by l Letters Patent is l. In va seed treating machine vhaving a pair of angnlarly disposed discharge spOuts,v the combination of a fan blower and its iny taliepipe, a pneumatic head having a sleeve .teiescoping with said pipe, a pair of angularlydisposed vintake boxes integral *with` said sleeve and forming part of the head, said `boxes having openinner faces for engagement. with the` outer-*Afwalls of said spouts, flangesv on said inner faces7 and means for attaching said boxesy to said spouts. 4 u v v o 2. In a seed treating machine the combination with a pair of angularly Adisposed lrectangular spouts, of a .pneumatic head comprising a pair of angularly disposed intake boxes haring open langed'walls adjacenty and contacting with complementary walls ofthe angular spoutsyattaching straps for securing said boxes to said spouts, afan blowerr and an intake pipe therefor, and -a sleeve on said head telescoping with the free end of said intake pipe.
